Electrostatic spray coating method is almost identical to the working principle of electrostatic powder coating method and is generally liquid coatings except that the powder coating is dispersed, rather than atomized. It is by electrostatic powder spray gun to the paint, while in the dispersion of negatively charged powder particles, the powder particles are charged by the effect of gas flow (such as centrifugal force or other forces) and the electrostatic attractive force, to the ground of the coated painted on the matter, and then heated and melted cured film. Electrostatic powder coating method is the dominant position of the powder coating method in the field of industrial coating. Electrostatic powder coating spray equipment to the surface of the workpiece laser spraying equipment, in electrostatic powder evenly adsorbed on the surface paint spraying equipment, powder coating formation; powdery coating after high temperature baking stream Ping solidify into different effect of the final coating; spray painting process is better than in the mechanical strength, adhesion, corrosion resistance, anti-aging and so on. One. Surface preparation. Pre-treatment process quality directly affects the quality of the powder coating, pre-treatment is not good, causing the coating easy to fall off, bubbling phenomenon. Therefore, the first task must be stressed. (1) can be used for sheet metal stampings chemical pre-treatment method. Ie: go to rust oil → → washing → phosphate (or purified) and so on. Most surface rust or thicker workpieces spraying equipment, sand blasting, shot blasting and other mechanical methods to rust, but after a mechanical descaling should ensure that the workpiece surface clean and free of dirt. (2) putty. Scraping the workpiece defect extent conductive putty, sanded smooth after drying, you can be the next procedure. (3) protection (also known as shield cover). If some parts of the workpiece does not require a coating before preheating can be covered up to protect glue, etc., in order to avoid the spray paint. (4) to warm up. Generally do not need to warm up. If the coating layer is required a thicker iron spraying equipment, the workpiece can be preheated to 100 ~ 160 ℃, which can increase the coating thickness. Automatic sprinkler spray atomization: controlled by circulating water pump from the tank to a certain pressure spray nozzle exit, the role of the workpiece to achieve the effect of pressure on the bath before the next pre-treatment. Equipment is determined by the length of the conveyor line speed and processing process time of the product. Spray pre-treatment effect, energy province. However, large area, high investment.
